Canopus (Alpha Carinae)
Canopus lies almost due south of the brightest star of all, Sirius, and nearly 53° south of the celestial equator, so that it is a (south) circumpolar object, never setting for observers south of about 40° south. By the same token it is never visible from places north of about 37° N.
Canopus is a rare F-type yellow-white supergiant, big enough to stretch three-quarters of the way across Mercury's orbit. It may already have been a red giant, or it may still have to pass through that phase, before ending its days as a massive white dwarf, possibly with a neon-oxygen composition.
Arrakis (Dune)In Frank Herbert's 1965 novel Dune, Canopus is the home star of Arrakis (informally known as Dune).
